Geronimo Stilton: Creepella von Cacklefur

About the Geronimo Stilton: Creepella von Cacklefur series

Creepella von Cacklefur is Geronimo Stilton's gently spooky spin-off, following Geronimo's reluctant, easily-frightened adventures alongside Creepella von Cacklefur -- a cheerful, ghost-whispering mouse from a family of monsters and eccentric spooks who lives in a crumbling, genuinely haunted castle. Where Geronimo is anxious and rule-following, Creepella is fearless and delighted by the macabre, and the series mines the culture clash between them for most of its comedy, alongside real (if kid-friendly) ghosts, vampires, and haunted-house mysteries.

Each book is a standalone spooky mystery -- thirteen ghosts to solve, a haunted movie studio, a stolen ghost pirate treasure -- told in the same illustrated, colorful-typography chapter-book format as every Geronimo Stilton line, but leaning into gentle horror and gothic atmosphere the way Fear Street does for older Stine readers, just calibrated for a much younger audience. It sits as the horror-adjacent counterpart to the main series' contemporary mysteries.

Running 9 books from 2011 to 2017, Creepella von Cacklefur introduced one of Geronimo Stilton's most enduring recurring supporting characters, with Creepella herself continuing to appear in guest spots across other Geronimo Stilton lines even after this series concluded.
